Problems solved by technology

[0004] Although such a solution can increase the wind pressure of the range hood to a certain extent, in practical applications, such a series fan system requires a large change in the circuit structure of the range hood, and the design cycle is long, which is not conducive to large-scale promotion. application

Embodiment Construction

[0056] As mentioned in the background art, in existing range hoods, a series fan system is commonly used to increase the air pressure of the range hood, so as to better improve the exhaust air volume of the range hood and optimize user experience.

[0057] For the existing series fan system used for range hoods, due to the increase in the number of fans, manufacturers need to add a set of corresponding control circuits to control each fan in the range hood system while adding fans to the range hood. The working status of the fan; or, some manufacturers choose to redesign the control chip, so that the control chip that originally only needs to control one fan can control two fans at the same time.

[0058] However, no matter which of the above solutions is adopted, the circuit structure of the range hood needs to be greatly improved, and the design cycle is long, which is not conducive to large-scale popularization and application.

[0059] In order to solve the above technical...

Abstract

The invention provides a smoke exhaust and a series fan system and a control method thereof and a controller and a fan system. The series fan system for the smoke exhaust comprises a first fan, a second fan and a connector, wherein two ends of the connector are correspondingly connected to an air outlet end of the first fan and an air inlet end of the second fan; the connector comprises a controlswitch; the control switch is used for detecting the liquid property of a detecting point in the connector, controlling the working state of the second fan based on the fluid property in order to start the second fan as the first fan starts and stop the second fan as the second fan stops; the connector further comprises a throat shaped port; the section of an opening of the throat shaped port is less than that of openings of other parts in the connector; and the detecting point is positioned between the throat shaped port and the air outlet end of the first fan. According to the technical scheme, the system has the advantages that the mounting mode of the second fan is simplified on the premise that the firs fan is not changed; and moreover, the two fans can be interlinked to work, so thatthe working system of the whole series fan system can be effectively improved.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to a range hood, its serial fan system, a control method, a connecting piece, and the fan system. Background technique [0002] As the two key indicators to measure the performance of a range hood, wind pressure and exhaust air volume largely determine whether a range hood is popular with the public. As a result, when designing a range hood, manufacturers of range hoods will take wind pressure and exhaust air volume as the two major design reference factors, hoping that the final designed fan system will have a higher wind pressure, and, when the wind pressure is determined, In the case of a large exhaust air volume. [0003] In order to increase the wind pressure, an existing technical solution is to connect two blowers in series and place them in the range hood as a whole. However, in the existing series fan system, the on / off control of the two fans is realized th...
